GEORGE HAISS, OF NEW YORK, N. Y.

WAGON LOADER.

Application filed April 26,

To all whom it may concern:

Be it known that I, Gnonon HAISS, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county-of Bronx and State of New York, have invented a new and Improved Wagon-Loader, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in wagon-loading devices, and has for its primary object to provide a device of this character which is automatic in its operation.

A further object of the invention is to provide a device of this character in which the operation is continuous so long as there is any material to be operated upon.

A further object of the invention is to provide a machine particularly adapted to operate upon piled material, and to provide said machine with propelling means for con: tinuously moving the machine into the pile of material upon which it is working.

A further object ofthe invention is to provide means for feeding the piled material laterally into the path of the buckets of the elevating conveyer.

lVith the above and other objects in view, reference is had to the accompanying drawin s in which igure 1 is a top plan view of the machine;

Fig. 2 is a side elevation thereof;

Fig. 3 is a fragmentary sectional view Fig. 4 is a rear elevation.

Referring more particularly to the drawings, the dey ice comprises a frame 10, which is mounted upon steering wheels 11, and traction wheels 12. The reference character 13 designates a frame suspended from the main frame 10. The frame 13 is adapted to carry a motor of any suitable type not shown.

The motor shaft is designated by the reference character 14, and extending around a suitable ulley 15 carried by said motor shaft, is a c ain 16, shown in dotted lines in Fig. 2, and said chain is adapted to drive a. gear wheel 17 which in turn meshes wlth a gear wheel 18, which meshes with a gear wheel 19 carried by a shaft 20 shown in full Specification olLetters Patent.

lines in Figs. 3 and 4. This train of gearing forms the means by which the shaft 20 is rotated, and keyed to the shaft 20, as at21, but freely slidable thereon, is a. pinion 22.

Mounted in the frame 10, is a shaft 23, and keyed to said shaft is an external gear 24 and an internal gear 25. As best seen i Fig. 4, one of the traction wheels 12 is provided w th an external gear 26, and meshing with said external gear 26, is a pinion 27, which is mounted on the free outer end of the shaft 23. By this construction, it will be seen that when the pinion 22 is engaged with the ex ternal gear 24, the traction wheels 12 will be driven in one direction, and when the pinion 22 is engaged with the internal gear 25, the direction of movement of the traction wheels 12 will be reversed. It is to be understood that suitable mechanism not herein shown, will be employed to move the pinion 22 longitudinally of its shaft 20.

Superimposed upon and angularly disposed with respect to the frame 10, is a frame 27 which is pivotally mounted as at 28, in stanchions 29 carried by said frame 10. and extending transversely of the frame 27 at its upper end is a shaft 30, and at its lower end the frame 27 is provided with a shaft 31. Each of the shafts 30 and 31 carries two spaced sprocket wheels 32 and 33, and passing around said sprocket wheels are endless chain members 34, on which are mounted elevator buckets 35. These elevator buckets 35 are adapted to discharge their contents into a chute or the like 35' when at the'top of the flight, as more clearly shown in Figs. 1 and 2.

As shown in Figs. 1 and 4, the lower shaft 31 is extended on opposite sides of the ma chine as at 36, and secured. to said extended portions 36 of the shaft 31, are digging elements 37, which are angularly disposed in .such a manner that when they engage the material operated'on the same is moved centrally of the device to a position where it will be scooped up by the buckets 35 and elevated the desired height dependent upon the adjusted positionof the frame 27. These dig ing elements 37 are angularly disposed Wltl relation to the longitudinal center of the frame 10, and also with respect to each other, so that as the shaft 31 rotates, the said digging elements 37 will successively on age the pile of material operated upon as a ove described.

The reference character 38 designates a frame, which is connected at its upper end to the conveyer frame 27, and has its lower end provided with a perforation for the reception of the free end of the shaft extensions 36.

The upper shaft 30 is provided with a sprocket wheel 39, and passing around 'said 5 rocket wheel 39, is a driving chain 40, said riving chain also passing around a sprocket wheel 41 carried by a transversely extending shaft 42. Carried by the transversely extending shaft 42. 's a sprocket wheel 43, and passing therearound is a chain 44, which serves as the driving medium of the shaft.

By this construction it will be seen that the conveyer chain members 34 are driven by rotation of the shaft 30, which is obtained through the medium of the chain 40 and the sprocket wheel 43.

The mechanism for propelling the loader at reduced speed and in a direction in which it will be continuously moved into the pile of material being operated upon, is clearly shown in Figs. 3 and 4,.and with reference to said figures, it will be seen that the shaft 43' is provided with a bevel gear 45, which is fixed thereto and adapted to rotate there with.

Secured to one of the stanchions 29 is a bracket bearing 46 and suspended in said bracket bearing 46 and so arranged therein as to have a slight swinging movement, is a vertical shaft 47. The upper end of the shaft carries a bevel gear 48, which is adapt ed to rotate therewith, and secured near its lower end to the shaft 47, is a worm gear, 49.

Mounted on the frame 10, is a cam member 50, which is operated by means of a handie 51, and pivotally connected to said cam, as at 52, is acollar 53, the said collar being adapted to receive the lower end of the shaft 47.

By this construction, it an be seen that as the cam handle 51 is rocked as shown by the arrow and the dotted lines in Fi 3, the worm gear 49 will be moved into an out of engagement with the gear 54, which is carried by the shaft 23, and is adapted to rotate the same, and through the medium of the pinion 27 heretofore mentioned, drive the traction wheels 12.

Having thus described the invention, the operation thereof is as follows: \Vhen the pinion 22- is engaged with the external gear 24, the machine will travel in the forward direction, and when the pinion 22 is engaged with the internal gear 25, the direction of travel of the machine is reversed and the speed thereof is materially decreased. This method of propulsion is intended only for transportation of the machine from place to lace when the same is not in use.

11 order that the buckets may at all times be in a position convenient to the material to be elevated, it is desirous that the machine be moved at a considerably reduced speed toward the pile of material continuously during the operation of the elevator flight, and this is accomplished by movement of the cam handle 51 to the dotted line position in Fig. 3, in which position the worm gear 49 engages the gear 54 and drives the traction wheel 12 in the reverse direction, it being understood, of course, that the pinion 22 will have been first adjusted to the neutral position shown in Fig. 4. Inasmuch as it is only desirous to drive the machine at this greatly reduced speed and in a reverse direction during the operation thereof upon a pile of material, the last-mentioned mecha' nism is so arranged that it derives its power from the conveyer or elevator-driving mechanism, and would, therefore, only be operable during the operation of said conveyer or elevator, and is likewise dependent there on for its power.

As the machine is continuously driven into the pile of material to be operated upon, it will be seen that the digging elements 37 will segregate the material and move it to a point approximately parallel with the longitudinal center of the machine, in which position it will be engaged by the buckets 35 of the conveyer or elevator and removed.

By this construction and arrangement of parts, it is obvious that the machine herein described is practically continuous in its operation and is capable of greater capacities than are machines in which it is necessary to stop the elevating mechanism in order that they may be adjusted from time to time with relation to the pile of material operated upon.
